This is typical TPL type turbocharger, which is used for supercharging diesel engines between 1,250 and 18,000 kW.
The turbocharger is essentially a simple machine. The rotor consists of a radial flow compressor (C) and an exhaust axial flow turbine (T), on a single shaft. The bearings are located between compressor wheel and turbine disk.
At C1, the air enters the compressor through a sound absorber and, after compression, is fed through a spiral-form air outlet housing, to the engine (C2). The exhaust gas from the engine flows into the turbine at T1 and leaves the turbocharger at T2.
The housings are divided vertically to the shaft, which runs through their centers. They can thus be reciprocally rotated, and the inputs and outputs for air and gas can be matched to the engine requirements.
